The side menu shows the version of Penahak you are using, written as v and a number. When you contact Penahak support about a problem, give this number: it tells them which changes your company already has.
The changelog page
The changelog page lists, version by version and newest first, what Penahak changed: new screens and improvements and bug fixes, in a few words each.
Open it by adding /changelog after your company code in the address (for example .../YOURCOMPANY/changelog). No sign-in is needed.
It is not in any menu: Penahak support can give you the address.
While it loads the page shows Loading.... If the list cannot be read it shows Error: Failed to load changelog: try again later and tell Penahak support if it stays.
